BRAIDING MACHINE Filed April 4, 1934 of the larger circle.

50 and two adjacent curved ways.

Patented Dec. 4, 1934 UNITED STATES PATENT OFFICE Application April 4, 1934, Serial No. 718,987 In Switzerland December 9, 1932 2 Claims.

The present invention relates to improvements in braiding machines and particularly to an arrangement of the driving gear of the shuttle carriers in braiding machines in which these driving 5 gears are arranged around a central gear in two groups on two concentric circles of different diameters where the wheels of the smaller circle are meshing with the central wheel and are inserted alternately between and meshing with the wheels In this arrangement the raceways of the wheels of the smaller circle are connected to the raceways of the wheels of the larger circle and to the raceway of the center wheel by means of interchangeable rotatable switch plates either of the two way type or a mixed type having a central way and two adjacent curved ways.

The annexed drawing represents a working example of an arrangement according to the present invention:

In the drawing a group of driving gears 1 is concentrically arranged around a centralgear 2. The gears 1 are alternately arranged on a smaller and on a larger circle. The driving gears 3 of the smaller circle mesh with the central wheel 3 and the gears 3 of the larger circle mesh only with the gears 3 All these gears are provided with notches 11 for the transporting and transferring of the shuttle carriers, not shown, from one raceway to an adjacent raceway. The distances between the notches are also chosen so that the notches of the different wheels will always meet each other. i

The raceways '7, 7 7 are cut into segmental raceway-plates 4 screwed fast to a base plate 5 by 40 means of screws 4 The supporting posts 6 of the driving gears are screwed fast to the bed plate 5. As means for transferring the shuttle carriers from one raceway to the other there are interchangeable and rotatable switch plates 9 9 fitted into the raceway plate 4 and are forming the connections between the raceways. The switch plates 9 are of the two way type having two ways crossing each other and the switch plates 9 are of a compound type having a central straight way The gear wheel 10 arranged on the larger circle serves as driver for all other wheels. The raceway of this wheel 10 is connected by a switch plate 8 of the compound type with the raceway of the next wheel '7 disposed on the larger circle.

In the Fig. 1 there are shown in all ten drive wheels arranged on two concentric circles of different diameters around a central wheel. When counting from right to left the raceways of the third and fourth wheels and of the fifth and sixth Wheels are connectedwith the raceways of the adjoining wheels by compoundswitches in such a position that said two pairs are cut off and working each together independently from the rest. In a similar way the raceways of the seventh and ninth wheels are working together because the compound switches which connect the raceways of the adjoining wheels, that is of the center, the

sixth, the eighth and the tenth wheel, are in such a position that the raceways of these wheels are thrown out of cooperation.

According to the Fig. 2 cam plates 12 are rigidly connected with the drivers 1 and are adapted to adjust automatically the switch plates 9 by means of pins 13 provided on said switch plates.

What I claim is:

1. In a braiding machine the combination of driving gears having a notched circumference for the spool carriers and each cooperating with a circular raceway said combination comprising a central driving gear, and two groups of mutually intermeshing drivers arranged around said central wheel on two concentric circles of different diameter, only the wheels of the smaller circle meshing also with the central wheel, and interchangeable rotatable switch plates of a cross type and a compound type inserted between the raceways of intermeshing gears and adapted to include or exclude the adjoining raceway accorda ing to the adjusting of said switches.

2. In a braiding machine according to claim 1 and in combination cam plates rigidly connected to the driving gears and pins attached to the switch plates both adapted to effect the automatic adjusting of the switch plates bythe driving gears.
